Remote Matrix Sentence Test on Uncalibrated Consumer Devices: Test-Retest Reliability and Laboratory Agreement in Normal Hearing

This study investigates the impact of uncalibrated consumer hardware on the outcomes of the German Matrix Sentence Test (GMST) in a remote setting. Speech-in-noise tests like the MST are relevant in audiology, as they better reflect everyday listening conditions compared to pure-tone audiometry....

The remote Matrix Sentence Test on uncalibrated consumer devices shows acceptable test-retest reliability and lab agreement in normal-hearing listeners, supporting its potential use for remote speech-in-noise screening, though validation in hearing-impaired populations is still needed before clinical adoption.

Validating remote, uncalibrated speech-in-noise testing could significantly lower barriers to hearing screening and monitoring outside clinic settings, with implications for teleaudiology service delivery.

1. 01Remote German Matrix Sentence Test administered on uncalibrated consumer devices showed good test-retest reliability.
2. 02Lab agreement was acceptable, suggesting remote and in-clinic results are comparable in normal-hearing adults.
3. 03Study population was normal-hearing participants — results may not generalize to hearing-impaired individuals.
4. 04Published in Trends in Hearing, an open-access audiology journal.
5. 05Findings support the feasibility of teleaudiology speech-in-noise testing without specialized equipment.
